Problem description:
There is a story in The Romance of The Three Kingdoms that Zhang Yide Changban Bridge made a scene and Liu Yuzhou defeated Jiangjinkou.
Where is Jiangjin here now? Is it the same place as Jiangjin in Chongqing now?
Analysis:
I don't think so. This Jiangjin is not another Jiangjin.
"Tianjin" means ferry, and there should be many such place names.
Secondly, Jiangjin County has a history of 1500 years. In the past, it was named Jiangzhou and Jiangyang. In 487 AD (the fifth year of Qi Yongming), Jiangzhou moved from the county seat (now Chongqing) to Jixikou (now Jiangkou). In 557 ad
Once again, "Liu You urgently transferred the Danyang satrap Wu Jing used by Yuan Shu to Jiangbei, sent Neng Fan and Yu Ertun to Hengjiangjin (now southeast of Anhui County), and Zhang Yingtun took advantage of the situation (now east of Anhui County) to refuse Jason Wu." (from awmhe/archiver/? tid-74933)
Based on this, I draw three conclusions.
By the way, you have a lot of question marks and not many points.
But your thinking should be fine, so the Jiangjin I gave you is not what you want.
But this Jiangjin is still not another Jiangjin. Here's a clue, which should suit your idea.
146 Jiangjin Port, south of Jingzhou Jiangling, Yangtze River Ferry. Across the river from the south bank.
At the same time, Jiangzhou was also mentioned in Shu, and I guess it is Jiangjin now.
Look at this post, I hope it will help you.
